[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the rotating body of the machine, reduce the friction coefficient during its movement, and ensure its rotational accuracy. When installing a bearing, it is usually installed inside a hole opened on the surface of a plate by means of riveting. And during installation, it is necessary to align the bearing with the opened hole. The processing table surface can usually perform central positioning on the raw material plate for installation. The bearing is arranged above the plate before riveting, and after riveting, the pressing device will fit with the top of the plate, resulting in the inability to perform central positioning on the outside of the bearing on the processing table surface. Generally, during installation, general riveting equipment only aligns manually, resulting in the bearing not being accurately set at the axis position, and causing damage to the bearing during the riveting process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-3 , the present invention provides a bearing riveting machine, which includes a processing table 1. Support legs 2 for support are installed at the bottom of the processing table 1. A side plate frame 3 is installed on the left side wall of the processing table 1. A reinforcing frame 4 is installed at the position where the processing table 1 and the side plate frame 3 are in contact. A top plate 5 is installed at the top of the side plate frame 3. A riveting hydraulic cylinder 6 is installed at the bottom of the top plate 5. A positioning port 7 is opened at the top of the processing table 1 and directly opposite to the riveting hydraulic cylinder 6. A bottom plate 8 is installed at the bottom end of the side plate frame 3. A positioning device 9 is arranged at the top of the bottom plate 8 and directly opposite to the positioning port 7.

[0019] Furthermore, the positioning device 9 includes a positioning cylinder base 91, a driving motor 92, a positioning transmission shaft 93, a bottom support plate 94, a bottom limit sliding groove 95, a positioning bracket 96, a limit plate 97, an axial limit sliding groove 98, and a positioning sliding seat 99. The positioning cylinder base 91 is installed on the top of the bottom plate 8. The driving motor 92 is installed at the bottom of the bottom plate 8. The output end of the driving motor 92 extends into the interior of the positioning cylinder base 91. The positioning transmission shaft 93 is installed at the top of the output end of the driving motor 92. The bottom support plate 94 is clamped inside the positioning cylinder base 91 and sleeved outside the positioning transmission shaft 93. The bottom limit sliding groove 95 is opened at the top of the bottom support plate 94. The limit plate 97 is installed inside the positioning cylinder base 91 and at a position close to the middle. The axial limit sliding groove 98 is opened at the top of the limit plate 97. The positioning sliding seat 99 is slidably clamped inside the axial limit sliding groove 98. The positioning bracket 96 is movably inserted into the positioning sliding seat 99. The bottom end of the positioning bracket 96 is clamped inside the bottom limit sliding groove 95.

[0020] Furthermore, the bottom limit sliding groove 95 is in a spiral shape. The inner end of the axial limit sliding groove 98 points to the center position of the limit plate 97. Through the cooperation of the axial limit sliding groove 98 and the positioning sliding seat 99, the positioning bracket 96 can only move along the notch position of the axial limit sliding groove 98.

[0021] Furthermore, there are three positioning brackets 96 in total. Through the cooperation of the three positioning brackets 96 to support from the inside to the outside of the bearing, the axis of the bearing can be in the central position.

[0022] Further, a threaded ring is provided on the inner wall of the positioning cylinder base 91, and a threaded groove adapted thereto is provided on the outer wall of the bottom support plate 94. When the bottom support plate 94 rotates, it will move upward under the restriction of the cooperation between the threaded ring and the threaded groove.

[0023] Further, the positioning transmission shaft 93 is hexagonal prism-shaped. The driving motor 92 drives the side plate frame 3 to rotate. When the positioning transmission shaft 93 rotates, it will drive the bottom support plate 94 to rotate synchronously, and the bottom support plate 94 can slide up and down along the outside of the positioning transmission shaft 93.

[0024] During use, the installation raw material plate is placed on the top of the processing table 1, and the installation hole position is adjusted to the central position. Then, the bearing to be installed is placed on the top of the raw material plate. Then, the driving motor 92 is started. The driving motor 92 drives the positioning transmission shaft 93 to rotate. When the positioning transmission shaft 93 rotates, it drives the bottom support plate 94 to rotate. When the bottom support plate 94 rotates, it moves upward under the restriction of the threaded ring on the inner wall of the positioning cylinder base 91. When the bottom support plate 94 moves upward, it pushes the positioning bracket 96 to move upward along the inside of the positioning slider 99, so that the top end of the positioning bracket 96 passes through the positioning port 7 and the hole on the surface of the raw material plate and extends into the inner axis center of the bearing. At the same time, when the bottom support plate 94 rotates, it will push the lower end of the positioning bracket 96 to move outward through the restriction of the bottom limit chute 95, so that the positioning bracket 96 drives the positioning slider 99 to move outward along the axial limit chute 98. Through the outward movement of the three positioning brackets 96, the bearing is supported from the central position to the outside, so that the bearing is located at the central position, and the bearing is kept vertical under the support of the positioning bracket 96. Then, the driving motor 92 stops rotating and remains stationary. Then, the riveting hydraulic column 6 is started for pressing work. The bottom output end of the riveting hydraulic column 6 first contacts the top of the positioning bracket 96 to compress the top end of the positioning bracket 96 until the bottom output end of the riveting hydraulic column 6 contacts the top of the bearing. The bearing is vertically pressed into the installation hole of the raw material plate through the riveting hydraulic column 6.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
